2. An easy electric start eliminates the need to pull a rope.
It also offers one of the longest life expectancies in the industry, with over 3,000 hours of runtime. Guardian
Ultra Source portable generators feature an electronic governor, which maintains steady speed and eliminates
voltage drop when loads are applied. This, as well as the automatic voltage regulator, provides a smooth rate
of electricity, which is especially important for sensitive electronic devices such as computers.
For added convenience and safety when you need it most, the generator comes with a pre-wired 16-circuit, 60
Amp indoor rated manual transfer switch, power cord and outdoor connection box. This makes it easy to use it
to supply power during an outage. With up to 16 selected circuits already pre-wired to the transfer switch, all
that's required is to start the generator and plug it in. By flipping a single switch, the utility is locked out and
the load is transferred to the generator.
A large, 16-gallon capacity fuel tank give the generator a 10-hour run-time at half-load capacity, ensuring you
have the power you need. An easy electric start eliminates the need to pull a rope. A simple push of the ignition
and an automatic ignition timing sets the spark for easy starting and optimum operating performance. The
generator runs on gasoline and meets all EPA emissions requirements.
To keep your electrical equipment running, the generator includes nine outlets, including a 50 Amp high power
outlet, three twistlock plugs and two GFCI protected duplex outlets. The generator also includes heavy-duty
13-inch all terrain tires, ensuring that you'll get the power to where you need it the most, a full 1.25-inch
tubular frame, battery charge cables and a maintenance-free battery. The generator measures
38.5-by-30.75-by-48.5 inches (HxWxL), weighs 525 pounds and is backed with a 2-year limited warranty.
